Another critical thing of the pineal gland function is that its act as a compass, it gives us our direction, it helps us to orientate ourselves to our environment into the various places of the world. And it's a secretory organ: meaning that it puts out or it secretes two hormones: one hormone during the day and the other hormone during the evening hours—melatonin. The pineal gland produces two hormones: melatonin at night and serotonin during daylight.
Melatonin, let's take a look at this hormone. The pineal gland produces a hormone called melatonin at night. Melatonin is produced, then release in the blood during nighttime.
The other hormone produced by the pineal gland is called serotonin, which is produced during the daylight hours, starting at dawn. So you can see the inverse relationship these two hormones have with each other: serotonin produced during the day and melatonin produced during the night. They have opposite function to each other.
The Egyptian called the pineal gland the “wdjt eye” or the “sound eye”. They also called the pineal gland third eye the “ureus,” which means the snake or the Cobra. Furthermore, they called the pineal gland the eye of Heru, which at that time was compared to Jesus the Christ—the so-called “son of God”. These were the different terms that the ancient Egyptians had for the pineal gland third eye.
What types of people study the pineal gland the third eye?
The types of people that do research on this very important organ; one person that deals with the pineal gland or studies the pineal gland is the endocrinologists; this is because the pineal gland is an endocrine gland, it secretes hormones.
